CJ Recht Mexican Cantera Opal and 14k Gold Necklace
Truly one of a kind, this necklace features a stunning, crystal clear Mexican Cantera Opal in a glowing tangerine color. This huge marquis shaped stone is set simply, in long prongs on marquis shaped disc of 14k recycled gold with an irregular scalloped edge. The stone, about 1 1/4 inches long is beautifully cut by my favorite German stone cutter, with a top ridge. The photos really don’t do it justice. The pendant is shown on a heavy 14k gold vintage watch chain. Price on request….
